Race information

Tri Dash is the leading grass-root triathlon series in Thailand.

For hundreds of triathletes, Tri Dash was their first triathlon race experience and has prepared them for longer and tougher triathlons later on.

All in all, the Tri Dash races are great for those new to triathlons but also a great challenge for seasoned athletes to test their speed, and everyone – athletes and staff – are helpful and friendly, creating a race atmosphere.

Athletes are not required to complete the whole distance the first time. You can always cut the swim, bike, or run short. Consequently, next time when you know what to expect and can try the whole distance; it is all about just giving it a go. We would much rather you just came out and have some fun than never trying.

Course maps

The swim is done in a 50-meter pool and participants with similar swimming ability are set off in groups.

The pool is shallow for the whole length so if an athlete is not a great swimmer they can walk sections of the swim.

The bike is on a closed road around the golf course so there is very little chance of cars and motorbikes.

The run is an out and back on the same road as the bike course.
